Question

Darwin himself poses a question in the first page of this reading:

"How have all those exquisite adaptations of one part of the organisation another part, and to the conditions of life, and of one organic being to another being, been perfected?"

Answer Darwin's question above based on your reading: outline in a single paragraph the logic of the process of natural selection. Be sure to articulate all of the necessary steps in the process. (Please avoid the shorthand phrase "survival of the fittest" in your answer!)

Answer 1

ANSWER: As described by Darwin, evolution is stated as "descent with modification," that says the species change over time, give rise to new species, and share a common ancestry.This he named as natural selection. Due to lack of resources organisms with heritable traits with favorable survival and reproduction will tend to leave more offspring than their peers, causing these particular favoured traits to increase in frequency over generations. Thus these species which have evolved have the best genetic fitness for the environment will have offsprings that can compete better in the future environment and are more perfect than others. Well we can say that these species are well adapted in the changing environment. These evolved and well adapted species must have some variations in heritability to sustain existence.
